Feminax Express tablets contain 342 mg of ibuprofen, an anti-inflammatory painkiller. The form of ibuprofen used (ibuprofen lysine) acts slightly faster in the body than regular ibuprofen. You can take it up to three times a day as required; ensure you leave at least 4-6 hours between doses, with a maximum of 6 tablets in 24 hours. It is important that it is taken with food, as the medication alone can cause stomach irritation. It is suitable for children, adolescents, and adults over the age of 12 years.

Doctor’s advice

Who is it for?

Feminax Express is a useful medication for relieving mild to moderate pain, such as pain associated with headache and migraine, menstruation, backache, muscular pain, dental pain, cold and flu symptoms, and a sore throat.

If you are between 12 and 18 years old and require treatment for longer than a few days, or if your symptoms are severe, it would be worth speaking to your doctor routinely. If you are over 18 and have been using this product for longer than 5 days, it would be worth discussing with your doctor.

How does it work?

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) from the same family as aspirin and naproxen. Because of this, ensure you aren’t taking ibuprofen alongside other anti-inflammatories, as this can cause issues such as stomach ulcers.

Ibuprofen’s anti-inflammatory effect works by blocking the body’s production of substances called "prostaglandins", which are released in response to illness or injury. Prostaglandins can cause pain and inflammation to notify the person they are unwell. NSAIDs can stop pain, inflammation, and even fever by stopping prostaglandin production.

Ibuprofen also has a minor antiplatelet effect, which means it stops the blood from clotting. Seek the advice of a pharmacist or doctor if you are on any medications that may affect bleeding.

Pharmacist recommended products

Are there any side effects?

As with all medications, some people are bound to get unwanted side effects. Some of the common ones with ibuprofen include indigestion and heartburn, as ibuprofen can irritate the lining of the stomach, especially when taken for more than a few days. If you are taking ibuprofen regularly or getting side effects, then you should stop and speak to your doctor about stomach protection to prevent stomach ulcers.

Should anyone avoid taking it?

Like all medications, don’t take them if you have previously had an allergic reaction to the medication, if you have severe kidney or liver problems, or if you have other medications or medical conditions that you would normally discuss with your doctor or pharmacist before starting something new. If you are asthmatic and haven’t had anti-inflammatory medications, they can sometimes cause an acute asthma attack, so it is best to speak to your doctor or pharmacist first.

Do not take ibuprofen if you are trying to get pregnant or are already pregnant, as there is not enough information about safety during pregnancy. You should avoid taking ibuprofen if you have a known stomach ulcer or inflammatory bowel disease.
